Another David who is enthusiastic about sheds is David Sproule from St Albans, Hertfordshire, who joked about the former PM's hut: "His shed is nothing compared to mine - he's just starting out in the world of sheds."

He had a recording studio and music room installed in his garden last year, which he christened 'The Shedio'.

"The top of the garden was just nettles and brambles - dead space," said Mr Sproule, who plays in a rock band.

He admits his "four or five guitars - one more than my wife knows about anyway" and amplifiers used to clutter up the house and that he needed somewhere to play music.

Mr Sproule said The Shedio was "the best £6,000 I ever spent".

"I love having a shed - as long as you don't use it to keep smelly lawn mowers in, it's the perfect place to run and hide from the world," he said. "And my wife no longer has to listen to me rehearsing my music - so it's a win-win."
